Fetch API
A Web standard specification that defines how HTTP network requests and responses are made through the Fetch interface, providing interfaces such as Request, Response, and Headers.
Timeline (last 90 days)
The key names of the Headers interface are case-insensitive and are normalized on access, and it supports methods such as append, get, and has, and can be passed between Request and Response.
Replay XHR cannot correctly reproduce Fetch requests, which is the fundamental reason it was replaced by Resend.
The Fetch API is a new-generation network request interface standardized around 2015 alongside Service Worker, designed based on Promises.
Headers 是 Fetch API 提供的标准接口，用于表示 HTTP 请求/响应头，内部以规范化方式存储键值对（键名统一小写、合并重复项），并通过 get、set、append、has 等方法访问，而非属性读取。
JavaScript in the browser cannot create raw TCP/UDP sockets; all network communication must go through high-level APIs such as WebSocket, Fetch, and WebRTC.
